Gas delivery pipeline detection device

Abstract

The invention provides a gas delivery pipeline detection device. The device comprises concentration detection sensors, a fixed block, a processor, an alarm, a sending machine and a receiving machine.According to the device, the concentration difference value detected between the concentration detection sensors is calculated and analyzed by the processor, when the calculated concentration difference exceeds the set concentration difference range value inside the processor, it is showed that a section of pipeline leaks, the processor controls the audible and visual alarm to sound an alarm, andmeanwhile, information of gas leakage of the section of pipeline is sent to the receiving machine of a maintainer through the sending machine, the maintainer can quickly know a specific pipeline withgas leakage through a hot stamping digital identity on the fixed block, so that the section of pipeline can be repaired in time.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a gas delivery pipeline detection device. Background technique [0002] The urban underground comprehensive pipeline gallery is the underground urban pipeline comprehensive corridor, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting It implements unified planning, unified design, unified construction and management. It is an important infrastructure and "lifeline" to ensure the operation of the city. It implements unified planning, design, construction and maintenance. It is built underground in the city for the laying of municipal Municipal utilities on utility lines.

AI Technical Summary

Problems solved by technology

[0003] There are gas pipelines installed in the urban underground comprehensive pipe gallery, and when the gas is transported through the pipeline, there will often be gas leakage in the pipeline, which will not only cause waste of resources, but also cause fire and explosion accidents. The comprehensive pipeline corridor poses a great safety hazard. In order to detect the leakage of the pipeline in time, different natural gas pipeline leakage detection and alarm devices have emerged on the market.

[0004] Although the existing detection and alarm devices for natural gas pipelines can realize simple detection and alarm, the maintenance personnel only know that there is an air leakage in the pipeline, but it is difficult to judge which section of the pipeline has the air leakage, which causes troubles for later maintenance. The accuracy needs to be improved. At the same time, the existing detection and alarm devices can only detect the air leakage by hearing the sound from the alarm, and cannot feed back the air leakage to the maintenance personnel in time, thus becoming a waste of resources. Can cause fire and explosion accidents
